Acupuncture filament spunbond nonwoven geotextiles are made of polyester filaments into a network and by method of consolidation, the fibers are arranged in three-dimensional structure. Filament geotextile has good mechanical features, good permeability and resistant to corrosion, aging, With isolation, filtration, drainage, protection, stability, reinforcement and other functions, Able to adapt to uneven grass-resistant construction external damage, creep, long loads can still maintain the original features.

2, Feature

(1) strength - the same weight specifications, the tensile strength is higher than all the other non-woven needle;

(2) anti-ultraviolet light - has a very high UV resistance;

(3) resistance to extreme temperature performance - high temperature of 230o C, high temperatures and still maintain the integrity of the physical properties of the original structure;

(4) permeability and drainage plane - acupuncture geotextile thick and is formed with good drainage and vertical permeability plane was able to maintain this performance after many years;

(5) creep resistance - geotextile creep resistance than other geotextiles, so long-term good. It is resistant to common chemicals in soil erosion and corrosion of gasoline, diesel, etc.;

(6) elongation - at a certain stress the geotextile have good elongation, so that it can adapt to the irregular substrate surface irregularities;
